I have noticed that when I have 5 or less bars of data in my bar graph the x-axis automatically adds in extra ticks:
What I want is something like this:
Is there any way I can force matplotlib to generate just one tick label per bar for the first graph?

MatPlotLib with Python Using subplot() method, add a subplot to the current figure. Plot x and log(x) using plot() method. Set the label on X-axis using set_label() method, with fontsize=16, loc=left, and color=red. To set the xlabel at the end of X-axis, use the coordinates, x and y.
Tick formatters can be set in one of two ways, either by passing a str or function to set_major_formatter or set_minor_formatter , or by creating an instance of one of the various Formatter classes and providing that to set_major_formatter or set_minor_formatter .
The bar method takes a parameter align. Set this parameter as align='center'. align aligns the bars on the center of the x values we give it, instead of aligning on the left side of the bar (which is the default).
Then use the xticks method to specify how many ticks on the x-axis and where to place them.
import matplotlib.pyplot as plot
x = range(1, 7)
y = (0, 300, 300, 290, 320, 315)
plot.bar(x, y, width=0.7, align="center")
ind = range(2, 7) # the x locations for the groups
plot.xticks(ind, x)
plot.axhline(305, linewidth=3, color='r')
plot.show()
